This paper presents a careful investigation of the three popular calibration weighting methods: (i) generalised regression; (ii) generalised exponential tilting and (iii) generalised pseudo empirical likelihood, with a major focus on computational aspects of the methods and some empirical evidences on calibrated weights. We also propose a simple weight trimming method for range‐restricted calibration. The finite sample behaviour of the weights obtained by the three calibration weighting methods and the effectiveness of the proposed weight trimming method are examined through limited simulation studies. 相似文献

In conventional social productive efficiency measurements that consider the production of undesirable outputs such as CO2, a DEA-based non-parametric method of production possibility frontier (PPF) identification coupled with the directional distance-function approach a-la Luenberger (1992) is typically employed. This paper shows that the discrepancy between parametric and non-parametric methods of PPF identification in social inefficiency measures can be non-negligibly large when the number of observations is small or the data are not well-scattered. By using the same data as Ha et al. (2011), who used non-parametric PPF identification to measure the social efficiency of Japan's inter-city transport services with lifecycle CO2 as the undesirable output, this paper demonstrates that adopting parametric PPF identification instead can result in considerably higher inefficiency measures for decision making units (DMUs) with relatively large undesirable outputs. 相似文献

This study empirically tests a model of associations between family-domain variables and willingness to accept an international assignment, and applies the general model to sub-samples of men and women to examine gender differences in the pattern of relationships. We further explore these patterns in culturally similar and culturally distant country destinations. Analyses conducted with a sample of 148 men and 79 women employed MBA graduates from dual-earner couples revealed that perceived spouse willingness to relocate, beliefs regarding spouse and couple mobility, relative income, and the presence of children are associated with willingness to accept an international assignment. Moreover, consistent with social role theory, significant gender differences in willingness were found across low and high cultural distance country destinations. 相似文献

We investigate whether the activity of financial firms creates value and/or risk to the economy within the asset pricing framework. We use stock return data from nonfinancial firms listed in the first section of the Tokyo Stock Exchange. The value-weighted index that is solely composed of nonfinancial firms is augmented with the index of the firms from the financial sector, and we estimate multivariate asset pricing model with these two indices. We note that our procedure can simultaneously take into account the cross-holding phenomena among Japanese firms, especially between the financial sector and the nonfinancial sector. Our augmented index model performs well both with cross-sectional Fama and MacBeth regression test and GMM test. Our two index model with additional Fama and French's HML factor can capture cross-sectional variations of the returns of sample portfolios better than the original Fama and French model can, when measured by Hansen and Jagannathan distance measure. We find that this additional new sector variable can be a substitute for Fama and French's size factor, but not related to the bond index return. This variable has similar factor characteristic as money supply growth or the term structure, but the latter variables contain more information than the former. Morever, our financial sector model helps explain the return and risk structure of Japanese firms during the so-called bubble period. 相似文献

The purpose of this research is to enhance knowledge about service recovery by investigating the feelings of psychological distance in the relationship between customers' perceptions of service recovery efforts of the perceived justice dimensions (distributive, procedural, and interactional justice) and attitudinal responses such as satisfaction with service recovery effort and trust in the firm. The results of structural equation modelling analyses suggested that consumers who had positive justice perceptions were likely to exhibit positive attitudinal responses. Consequently, the positive attitudinal responses generated positive word-of-mouth intention about their experiences and encouraged them to continue the service. 相似文献
